1.Jsoup可以使用類似于CSS或jQuery的語法來查找和操作元素.

2.實例如下：

public static void main(String[] args) throws Exception{// 創(chuàng)建httpClient實例CloseableHttpClient httpClient = HttpClients.createDefault();// 創(chuàng)建httpGet實例HttpGet httpGet = new HttpGet("http://www.cnblogs.com");httpGet.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0");CloseableHttpResponse response = httpClient.execute(httpGet);String content = null;if(response != null){HttpEntity entity = response.getEntity(); content = EntityUtils.toString(entity, "UTF-8"); // 獲取網(wǎng)頁內(nèi)容Document document = Jsoup.parse(content); // 解析網(wǎng)頁，得到文檔對象// 1.查找所有帖子DOMElements elements = document.select(".post_item .post_item_body h3 a");for(Element ele : elements){System.out.println("博客標(biāo)題：" + ele.text());}System.out.println("------------------------分割線------------------------");// 2.查找?guī)в衕ref屬性的a元素Elements hrefElements = document.select("a[href]");for(Element ele : hrefElements){System.out.println(ele.toString());}System.out.println("------------------------分割線------------------------");// 3.查找擴展名為.png的圖片DOM節(jié)點Elements imgElements = document.select("img[src$=.png]");for(Element ele : imgElements){System.out.println(ele.toString());}System.out.println("------------------------分割線------------------------");// 4.獲取tag為title的第一個DOM元素Element titleEle = document.getElementsByTag("title").first();System.out.println("標(biāo)題為：" + titleEle.text());}if(response != null){response.close();}if(httpClient != null){httpClient.close();}}
